I deployed my ejbs in the JBoss server,
When deploying/at the time of JBoss start up i got error messages when there is BAD INTERNET CONNECTION.

It works fine when net connection is fine,

how can i remove exception occuring in server.?

Actually server tries to get DTDs from sun's site ,
how can i point to dtds present in JBoss directories ?
or prevent server from going to suns site for dtds ?

error i got is like this
